// @endif outputs whatever is behind the @endif token

[doberkofler]

When preprocessing the following code without the DEBUG environment variable set:

'use strict';
var pp = require('preprocess');
var text = '//start\n// @ifdef DEBUG\nvar some;\n// @endif DEBUG\n//end';
console.log(pp.preprocess(text, {}, {type: 'js'}));

you would imagine, that the //start and //endlines will be returned but instead the following text will be returned:

//start
DEBUG
//end

Unfortunately preprocess will output whatever text is behind the @endif token and this seems very wrong to me.

I break out \nvar some;\n// to a separate variable, and wrap it in @ifdef to deal with that. Agree that it's surprising behavior.
